Error on making a project with m2e + eclipse indigo + springmvc-archetype

[Myke Enriq]

Basically I just want to make a project with the springmvc-archetype and run it.

Error 1: the automated generated pom.xml has one error in it : "Plugin execution not covered by lifecycle configuration: org.datanucleus:maven-datanucleus-plugin:2.1.0-release:enhance (execution: default, phase: process-classes)"


Error 2: when compiling and running on tomcat 6 it fails because of:

Caused by: java.lang.ClassNotFoundException: myke.enriq.model.MyEntity



The actual error stack trace:

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

IMPORTANT NOTE:
1) I do not change/add/delete anything from the pom.xml , or any other maven configuration
2) When I use other archetypes for other type of projects (spring ws , struts, etc) it works like a charm , no errors

[Mark Spritzler]

Yeah, I try to stay away from some of the archetypes. Some are really old. I might use the basic one, but even that doesn't even create the src main, test, java, resources directory.

[Myke Enriq]

so how do you create the basic spring+mvc (+ hibernate maybe) project structure , using the m2e plugin ??

We'll I haven't used m2e, so I would just do it manually. Create a directory, inside that directory create a src/main/java and a src/main/resources and a src/test/java and a src/test/resources directory. Then create a pom.xml file at the root directory and copy and past from some other project, or tutorial out there and you have the start of a maven project.

I'd add the spring jars as <dependency> and other jars that I need. There are many examples out on the web to just copy and paste from.

Or use Roo and use just the create project command to get a maven structure started with a pom file with many dependencies already in it.

[Bill Gorder]

Roo is the way to go if you want all the dependencies. If you use STS you can use the spring template project. Alternatively just use the standary maven web-app project archetype and add in your spring dependencies as Mark already said.
